Answer:
Step-by-step explanation:
For this case we have the following data given:
2.3 3.1 2.8
1.7 0.9 4.0
2.1 1.2 3.6
0.2 2.4 3.2
Since the data are assumedn normally distributed we can find the standard deviation with the following formula:
And we need to find the mean first with the following formula:
And replacing we got:
And then we can calculate the deviation and we got:
Answer:
A
Step-by-step explanation:
x+x+1+x+2=33
3x+3=33
3x=30
x=10
so x+1 =11
x+2 =12
Answer:
Step-by-step explanation:
<u>Given</u>
- Each deposit = $1500
- Interest rate= 5%
- Time = 4 years
- Compound number = annual
<u>Simple interest account</u>
- B = 1500*(1 + 4*0.05) = 1500*1.2 = $1800
<u>Compound interest account</u>
- B = 1500*(1 + 0.05)^4 = $1823.26
<u>Total balance</u>
- $1800 + $1823.26 = $3623.26
Answer:
Step-by-step explanation:
as x is direct to y hence
x∝y
also given x∝z combine these two equation we get
x∝y*z
now insert b as constant
x=b*y*z
as given x=20, y=3 , z=4 putt in above equation we get
b=20/3*4 =5/3 =1.666

Answer:
-1,325 ft below sea level
Step-by-step explanation:
0(surface level) - 1,500 = -1,500
-1,500 + 525 = -975
-975 - 350 = -1,325
